Specification forming part of Letters Patent No.

7 176,712., dated April25, 1876; application ea December 11, 1875.

ments in Harvesters; and We do hereby declare that the following is afull, clear, and exact description thereof, which will enable othersskilled in the art to which it pertains to make and use the same,reference being had to the accompanying drawing, and to letters ofreference marked thereon, which form a part of this specification.

Figure lis a side elevation of our improved harvester; Fig. 2, aperspective view of belt- Like letters in both figures of the drawingindicate like parts.

Thisinvention relates to the class of harvesters known as headers; andthe object of it is to avoid the difficulty heretofore experienced inadjustin g the cutters to enable them to out high grain; and theinvention consists of an adjusting-lever, having a reversible auxiliaryarm or link connected to the main frame, in combination with a standardattached to an extension of the tongue, constructed and operated so thatthe cutters can be elevated to out very high grain; also, of abelt-tightener, consistingvof slotted plates, belt-roller, set-screw,and standard, constructed and combined with the front beam ofthemachine, as will hereinafter be. more the end of lever A, theiroppositeends being,

made to embrace and have a pivotal connection with a fixed block, 01,attached to the front beam 0 of the machine. The tongue is provided withtheusual adjustable tillerwhcel E and lever-standard 01, having theusual holes to receive a pin for securing the lever A. FG are theslotted plates, pivoted together at e. Plate G is provided with thebelt-roller h, adjustable by means of a setscrew in the slot, andpivoted at its lower end to the front beam of the machine. Plate F isattached by a set-screw, t, to a fixed standard, It. These plates, asthus arranged, can be so adjusted, by moving plate F or the belt-rollerup or down, as to secure the tightening of the belt for running thegrain-carrier with the greatest nicety.

The arrangement of the adjusting-lever with the fulcrum-standard andextension of the tongue allows the frame to be shortened,

-so as to leave only space enough for the wheels to revolve in betweenthe rear and front cross-beams.

The operation of the adjusting-lever is as follows: When desiring -toout very high grain, lever A is released from the standard cl, and theend thrown up,.so as to reverse or 'throw down auxiliary arm B. (Seeoperation of the same in dotted lines of Fig. 1.) In this position thelever can be made to elevate the cutters so as to out very high grain.

Having thus fully described my invention, what I claim therein as new,and desire to secure by Letters Patent, is

1. An adjusting-lever, having'a reversible auxiliary arm or linkconnected to the main frame, in combination with a standard attached to.an extension of the tongue, substantial] y as and for the purpose setforth.

2. In a harvesting-machine, the belttightener, consisting of the slottedplates F G, adjustablebelt-roller h, set-screw i, and standardstantially as set forth.

In testimony that we claim the foregoing as our own' we have affixed oursignatures in presence of two witnesses. BENJAMIN G. TURNER. EDWARD A.OULBEBTSON. MALCOLM A. MGKIN NON Witnesses:
